Granular Urea (46-0-0): Specification & Supply
Product: Granular Urea (46-0-0)
Also known as: Urea 46-0-0, Granular Urea N46
Chemical formula: CO(NH₂)₂
Standard grade: 46-0-0
Granular Urea Overview
Granular urea is described on this page as the most widely used solid nitrogen fertilizer in the world, containing 46% nitrogen — the highest concentration among common dry fertilizers. It is valued for nutrient density, cost-effectiveness and use across a wide range of crops and soil types.
The existing text states that urea is produced by reacting ammonia with carbon dioxide under high pressure and temperature, followed by granulation to form hard, free-flowing granules.

Key Benefits
- Highest nitrogen concentration
- among solid fertilizers — reduces transport, storage, and application costs per unit of nitrogen.
- Cost-effective
- — One of the most economical sources of nitrogen available.
- Versatile application
- — Suitable for broadcasting, banding, blending, and (with care) fertigation or foliar use (low-biuret grades preferred for foliar).
- Promotes vigorous growth
- — Supports rapid vegetative development, higher yields, and improved crop quality.
- Easy handling
- — Granular form allows accurate mechanical spreading and bulk blending.
- Wide crop adaptability
- — Effective on virtually all crops and soil types when managed correctly.
Recommended Applications
- Highly suitable for:
- Cereals: Wheat, rice, maize/corn, barley
- Oilseeds, sugarcane, cotton, and most field crops
- Vegetables, fruits, and horticultural crops
- Pasture, forage, and grassland management
- Forestry and reforestation programs
Packing and Shipping
- 50 kg moisture-resistant bags
- 500–1,000 kg jumbo bags (FIBC)
- Bulk (loose) delivery for large-scale agricultural and industrial use
Storage and Handling
- Store in a cool, dry, well-ventilated warehouse protected from moisture.
- Keep bags sealed and stacked on pallets to prevent caking.
- Avoid contact with ammonium nitrate and strong oxidizers.
- Use standard personal protective equipment; urea dust can cause mild irritation.
